Second range trip:
-Adjusted the TT Diamond Trigger down
-Check all screws: action and scope rail
-Replaced scope with a Leupold Mark 5 HD 3.6-18x44
-Cleaned barrel
-Used a more rigid rear rest and braced bipod
-Focus on fundamentals
Overall, a little better, maybe. Seems like the first groups at the beginning of each row/far left is where I'm doing something noticeably wrong. The second and third group in each row are better. Still not smiling. I'll keep at it.
